DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to an improvement of a harvester equipped with a binding machine for binding a plurality of threshing waste culm bundles on the feeding end side of a feed chain.

2. Description of the Related Art Conventionally, in a harvester, a binding machine that binds a plurality of threshed waste culm bundles into a large bundle is attached to the end of the feed chain conveyance, and a binding machine that facilitates post-treatment of culms is provided. Harvesters are provided.

However, in this type of conventional harvester with a binding machine, unlike the case of the combine harvester, the culms that are fed to the knot side by the feed chain are not in the form of roses Since it is the discharged culm bundle, there are the following inconveniences.

That is, since the processing such as bundling of the culm bundles is performed intermittently in a state where the feed chain continuously supplies or moves the culm bundles to the knotting portion, the timing of feeding the culm bundles during the knotting operation is performed. If it is misaligned, the needle of the bundling machine will rush into the center of the subsequent culm bundle, causing a binding error, causing trouble such as clogging, or uneven number of bundles. is there.

Means for Solving the Problems Accordingly, the present invention is provided to a threshing machine in a harvester equipped with a binding machine that binds a plurality of threshed waste culm bundles to the feeding chain end side of a feed chain by operating a single rotation clutch. A counting device for counting the number of grain culm bundles and an culm bundle supply suspension means for temporarily interrupting the supply of the culm bundles to the binding machine are provided in the thresher, and the counting device has a predetermined number of bundles set in advance. The above problem is solved by the interlocking structure of the counting device, the culm bundle supply suspending means, and the binding machine so that the exhaust bunching supply suspending means and the one-rotation clutch of the binding machine operate when counting Is what you are trying to do.

Action In the threshing work by the harvester, the operator continuously feeds the grain culm bundles to the threshing machine from the feed port of the threshing machine through the feed chain, but during this threshing work, the number of grain culm bundles supplied to the threshing machine is counted. It is always counted by the device.
Then, every time the counting device counts a predetermined number of bundles set, the culm bundle supply suspension means and the one-rotation clutch of the binding machine are activated, so that the supply of the culm bundles from the threshing machine to the binding machine side is performed. It becomes possible to perform the binding operation of the culm bundle by the tying machine in the state of being temporarily interrupted, and the needle of the tying machine rushes into the center of the succeeding culm bundle, resulting in a tying error or clogging. Problems such as the occurrence of troubles such as unevenness of the number of bundles or the like are eliminated, and a certain number of bundles are reliably bundled in a state where they are completely separated from the subsequent culm bundle.

FIGS. 13 to 16 show another embodiment of the culm bundle supply suspending means, in which when the threshing machine 2 is supplied with a predetermined number of grain culm bundles, the supply port 2a of the threshing machine 2 is opened. By closing and blocking the supply of the subsequent grain culm bundle, the supply of the discharged culm bundle to the binding machine N is interrupted. At that time, the grain culm bundle held by the feed chain 4 has completely finished threshing. After being fed to the binding machine N, the binding machine N is configured to start its operation to further ensure the number of binding bundles.

That is, every time a grain culm bundle is supplied to the supply port 2a of the threshing machine 2, the ratchet counting gear 12 is pushed and rotated by the pinching rail support pin 4b, and when the predetermined number of bundles is reached, the pin 12c is armed. The wire 44 is pulled to press 34, actuating the link 45 in the shutter box P. The link 45 locks the shutter 46 in the retracted state, but when the wire 44 is pulled, the link 45 rotates to release the locking portion 46a, and the shutter 46 moves to the ammunition 47.
This prevents the supply of grain culms by protruding into the supply port 2a.

On the other hand, as shown in FIGS. 14 and 15, a switch 48 is arranged so as to face the lower end of the arm 34, and a solenoid 49 connected to the clutch pin 36 is arranged in the clutch portion M of the binding machine N. The solenoid 48 and the solenoid 49 are connected via a delay mechanism O consisting of a timer 50 and a power relay 51. When the wire 44 is pulled, the switch 48 is turned on.
This signal enters the timer 50, delays the time until the last supplied grain culm bundle is threshed and falls to the binding machine N side, enters the power relay 51, and is further transmitted to the solenoid 49 to the clutch. The pin 36 is operated in the arrow direction in FIG. As a result, the pin 35 engaged with the clutch pin 36 rushes into the engagement hole 17a provided in the bevel gear 41 to start transmitting power to the binding machine N, and when the input shaft 37 makes one revolution, the pin 35 re-projects. Then, the clutch pin 36 in the standby state is contacted with the clutch pin 36, and the bevel gear 41 is disengaged. When the operation of the binding machine N is started, the wire 53 fixed to the needle a is pulled, and the link 54 becomes a fulcrum pin.
Rotating counterclockwise in FIG. 11 around 52, the shutter 46 retracts from the supply port 2a, and the locking portion 46a is locked by the link 45 to be in a standby state so that the grain can be supplied. become. 55 is the guide rail of the shutter 46, 5
6,57 are bullets and 58 are long holes.

FIG. 17 and FIG. 18 show that the culm bundles are bundled with an arbitrarily set number of bundles, and the dropper D is operated with an appropriate delay regardless of the weight of the bundles. ,
The number of bundles to be bound can be arbitrarily changed according to the medium bundle and the large bundle. That is, the threshing culm bundle is a switch 60 provided at the end of the feed chain 4 (see FIG. 1).
The counter 61 counts the number when the number of bundles is set, and when the number of bundles set by the number-of-bundles setting knob 62 reaches the number of bundles, the knob 62 outputs a signal to drive the solenoid 64 via the relay 63, so that the binding machine N The one-rotation clutch M (see FIG. 12) is actuated and the binding action is performed.

On the other hand, the signal passes through the timer 65 and drives the solenoid 66 with a certain time delay, whereby the stopper (not shown) of the dropper D is released and the bundle of discharged culms is discharged. When the dropper D is rotated and returned upward by the recovering ammunition 67 after discharging the bundle,
Switch 68 releases relay 69 from self-holding and solenoid
66 again holds the dropper D in the set position. 70 is an AND circuit.

In the above configuration, when a grain culm bundle is supplied between the feed chain 3 side of the thresher 2 and the feed chain 4 and the pinching rails 4a, the pinching rails 4a are lowered to lower ends of the rail support pins 4b. The unit advances the ratchet counting gear 12 in a bundle. When the number of bundles to be supplied reaches a preset number, the pin 12c protruding from the gear 12 contacts the arm 34 and the wire 29a.
Is drawn. Therefore, the clutch pin 29 connected to the wire 29a is pulled against the ammunition 29a and the clutch cam 26
The pin 27 and the clutch pin 29 provided on the clutch are disengaged, so that the pin 27 projects toward the large gear 17 side by the bullet 28 and fits into and is locked in the pin engaging groove 17a, so that the clutch cam 26 always rotates. It rotates together with the large gear 17 that is rotating. At this time, the link arm 32 that is in contact with the clutch cam 26 is
The clutch 21 engaged with the worm wheel 15 is disengaged by the shifter 31a fixed to the shifter shaft 31 due to the operation of a, so that the transmission of power to the drive shaft 20 of the feed chain 4 is stopped, and the rotation of the feed chain 4 is stopped. Motion stops. When the clutch cam 26 rotates as described above, the protrusion 26b causes the lever 33 to rotate about the pivot pin 33a, the wire 43 is pulled, and the one-turn clutch M of the binding machine N enters.
The binding machine N operates once. Now, when the large gear 17 makes one rotation, it is pulled out by the clutch pin 29.
26 stops after one rotation, returns to the state shown in Fig. 4, and the clutch
21 engages the worm wheel 15 to restart the drive of the feed chain 4.

Thus, during the threshing operation by the harvester, when a predetermined number of grain culm bundles are supplied to the threshing machine 2 side, the ratchet counting gear
12 counts it and the culm bundle supply stopping means operates, that is, the clutch 21 for connecting and disconnecting the power transmission to the feed chain 4 is automatically disengaged, so that the discharge of the culm bundle to the binding machine N is stopped. It becomes possible to perform the binding operation of the discharged culm bundles, so that unlike the conventional one, the middle of the succeeding discharged culm bundles are not bound and the number of bundles is not uneven, and it is completely connected with the succeeding discharged culm bundles. It is possible to reliably bind a predetermined number of bundles in the separated state.

If the counting device A is provided on the feeding start end side of the feed chain 4 as in this embodiment, it is easy for the operator to see, and the speed at which the bundle is bitten on the feed chain 4 can be adjusted as necessary. However, the mounting position of the counting device A is not limited to this.

Effect of the Invention As described above, the present invention is a harvester equipped with a binding machine for binding a plurality of threshing waste culm bundles to the feed end side of a feed chain by operating a single rotation clutch.
The thresher is provided with a counting device for counting the number of grain culm bundles supplied to the threshing machine and an culm bundle supply suspension means for temporarily interrupting the supply of the culm bundle to the binding machine, and the counting device is preset. The counting device, the culm bundle supply suspending means, and the binding machine are interlocked so that the exhaust bunching supply suspending means and the one-rotation clutch of the binding machine are activated when the predetermined number of bundles is counted. It is possible to perform the bundling operation of the culm bundle while the feeding of the culm bundle to the machine is stopped, and there is no binding error such as bundling the middle of the subsequent culm bundle or uneven number of bundles. There is an effect that a certain number of bundles can be surely bound.
